What are the lives of America's richest families really like? Their nannies see it all…

After a dysfunctional childhood as one of four kids born to teenage parents and raised "white trash" in poor Rhode Island, Stephanie Kiser finds herself a 22-year-old, first-generation university graduate drowning in student loan debt. To stay afloat, she surrenders her career-track PR job for a position as a babysitter to New York City's toddler elite.

The span of seven years takes Stephanie on a journey from working alongside a stay-at-home mum in her ten-million dollar Park Ave apartment, to a "no discipline" family, to the Kushners, world-class doctors and finally, to a position with a young couple - both high-powered lawyers - with three small kids.
